Introduction

  • The plant Embelia ribes is distributed throughout India, Malaya and South China.
  • ‘‘Vidanga’’, one of the important ayurvedic drugs, is widely used in indigenous system of medicine as an althelmintic, lterative and tonic since ancient times.
  • It is known as ‘‘birang’’ in Bengali, ‘‘vavading’’ in Gujarat and Maharashtra, ‘‘baberang’’, ‘‘baibidang’’ and ‘‘baibirang’’ in Hindi, ‘‘vaivalanga’’ and ‘‘vayuvidang’’ in South India and ‘‘babang’’ in Pushtu language.
  • LR 57,4 290 Present study was taken up to quantify and map the world scientific output in the area Embelia ribes, the aim being to offer an overview of research activity and to characterize its most important aspects and their evolution over the years.

Objectives of study

  • The specific objective of the present study addresses the following aspects: (1) Temporal evolutional of number of publications.
  • (2) Number of authors contributing each article and authorship pattern.
  • (3) Author productivity through the application of Lotka’s law and most prominent authors in the area of Embelia ribes.
  • (4) Output of different journals with their rank and the application of Bradford’s law as an indicator of the dispersion of scientific information.

Methods

  • Since the data were collected from various sources, 31 records were found as duplicates and were removed using EndNote’s duplicate removal application.
  • Given that the objective of the present study was to analyse all the journal articles published on, Embelia ribes the search was open and not limited to any time period, also known as (2) Time Period.
  • Therefore, books, proceedings, book reviews, etc. were all excluded.
  • Having applied the above restrictions a total of 332 articles were collected and data were than tabulated using SPPS 15.0.

Data analysis

  • The analysis of the present study focused mainly on the frequencies and percentages of publications.
  • In addition, however, the productivity of authors and journals was described using Lotka’s law and Bradford’s law of scattering, respectively.
  • The number of authors each contributing n articles is proportional to 1/n2, also known as The approximation is.
  • This law is often termed ‘‘the inverse square law of scientific productivity’’.
  • As an indicator of the dispersion of scientific output, Bradford (Bradford, 1934, 1948) proposed a model of concentric productivity zones with a decreasing information density.

Number of authors

  • The number of authors contributing to each article ranged from one to nine: however, Figure 1 shows, 18.37 per cent have a sole author while 36.75 per cent have two authors.
  • Articles with more than five authors account for 3.01 per cent of the total number of documents.

Author productivity

  • Table II shows the distribution of the number of articles published by each one of the authors, and reveals that whereas some authors contributed to as many as twenty-two articles others only contributed to one.
  • As can be seen, 73.86 per cent of authors only contributed to one article, those contributing to more than one, therefore, being much fever in number.
  • Only three authors published ten or more studies.
  • Lotka’s law has been applied to calculate the number of expected authors for a given number of published studies.
  • Putting the value of ‘‘n’’ as 2, the following results (Table III) has been derived.

Prolific authors

  • The most prolific authors of the subject Embelia ribes have been identified and ranked form greater to lesser contribution.
  • There are only three authors published ten or more articles.
  • The author with the greatest contribution in terms of research on Embelia ribes is A.O. Prakash contributing 22 articles, followed by Mathur and Das with 13 and 10 articles respectively.
  • Next position occupied by Atal, Chander, Munshi and Venkateswarul with eight article each.
  • The contribution of the most prolific authors with scattering in total number of journals is shown in more detail in Table IV.

Core journals in the subject

  • The 332 articles analysed in the present study were published in 140 journals from various scientific fields.
  • The most productive journals in terms of Embelia ribes are shown in more detail in Table V.
  • As can be seen the journals that have published the most articles on Embelia ribes are the Journal of Research in Indian Medicine, Yoga and Homeopathy, Indian Journal of Indigenous Medicines and Fitoterapia accounting for 4.81, 4.51 and 4.21 per cent of the total number of publications, respectively.
  • It has been observed that out of 332 articles published in 140 journals, 96 (29.35 per cent) articles were published in ten journals that may be considered as core journals in the subject Embelia ribes.

Bradford’s distribution

  • After applying Bradford’s law of scattering with respect to the variable ‘‘journal’’, three concentric zones were defined.
  • The core or zone 1 contained 96 (32.78 per cent of the total) articles that were published in ten journals.
  • According to Bradford’s law, the number of journals following successively in the three zones should be in the ration of 1: n:n2, while the ratio in each zone of the present is 10:36:99, which is nearly in accordance with the Bradford’s distribution.
  • The zone wise distribution of articles in different journals is shown Table VI.

Output of different institutions

  • An exhaustive analysis of the articles under study revealed that the various authors come from a wide range of institutions, including research institute, hospitals, colleges etc.
  • Bradford’s distributions of articles in different journals Zone Number of journals Number of articles First 10 96 Second 36 112 Third 99 119 Total 140 327 Bibliometric study of Embelia ribes 295 organizations, which have published the most articles on the subject of Embelia ribes (institutions with fever than three articles were not considered here).
  • The organizations with the highest productivity are the Jiwaji University and Banaras Hindu University, institutions involved in a total of 26 (7.83 per cent) and 21 (6.32 per cent) articles, respectively.
  • These are followed by the scientific output of the Pant University of Agriculture and Technology, the Captain Srinivasa Murthi Drug Research Institute for Ayurved and the Panjab University, whose output ranges from 16 to 12 articles and accounts for 11.74 per cent of the total number of publications.

Countries

  • In studying this variable, countries were ranked from greater to lesser productivity, taking into account that authors from different countries may contribute to the same article.
  • The country with the greatest output in terms of research on Embelia ribes is the India (63.86 per cent), followed by USA and UK, with a total of 29 (8.73 per cent) Table VII.
  • Most productive institutions Institution Rank Number of articles % Jiwaji University, Gwalior 1 26 7.83 Banaras Hindu University, Varanasi 2 21 6.33 Govind Ballabh.
  • Next come Japan (5.72 per cent), Italy (4.22 per cent) and Germany, the remaining countries publishing a total of 17 documents between them, accounting for 10.6 per cent of output.

Global distribution of journals

  • As pointed out that a total of 332 articles were published in 140 journals.
  • The most productive countries in terms of number of journals are shown in Table IX.
  • As can be seen, 57.14 per cent journals on the subject Embelia ribes have been published from India, followed by USA and UK with the 16 and 14 journals, respectively, accounting 21.42 per cent of the total number of journals.
  • Remaining 40 (28.57 per cent) journals have been published from 11 countries.

Discussions and conclusion

  • Throughout this study, an analysis of scientific output on the subject of Embelia ribes has been carried out in terms of frequencies and publications.
  • Taking specific objectives into account the following conclusions can be drawn: (1) Interest in the subject of Embelia ribes grew considerably during last quarter of the 20th century, particularly since 1980s, 1990 and 2000s.
  • (3) The number of authors contributing to each article range from one to nine, however, most articles involved collaboration between two or three authors.
  • According to Bradford’s law of scattering this distribution fits 1:n:n2, such that the most peripheral zone should contain a greater number of journal titles thanwas obtained in present study.
  • The most productive organizations were the Jiwaji University and Banaras Hindu University. (7) Although the authors contributing to the articles collected originating from 16 different countries, most output (91.26 per cent) was distributed across only five countries, the most productive being the India, which participated in 63.85 per cent of the publications studied.

TL;DR: MAPs have become “industrial products” with new concepts like phytotherapy and veterinary medicinal uses, aromatherapy, nutraceuticals, cosmeceuticals, and animal welfare uses widening the scope of the utilization.
Abstract: The history of Medicinal and Aromatic Plant (MAP) utilization dates back to the beginnings of mankind. Our forefathers used natural substances, they could find in nature, to ease, cure their sufferings, illnesses, to heal their wounds. This type of approach has survived in the Traditional Medicinal (TM) uses, until today, since nearly 80 % of the world population still relies on MAPs in their medications. The renaissance of MAP-use in the high-income countries of the world has brought about a different type of use in the form of Herbal Medicines (CAM). MAPs have become “industrial products” with new concepts like phytotherapy and veterinary medicinal uses, aromatherapy, nutraceuticals, cosmeceuticals, and animal welfare uses widening the scope of the utilization. New, innovative, value added applications include their use in functional foods, animal husbandry, as well as plant protection in agriculture. In this regards the versatile utilization of essential oils is promising. Modern approaches in production and uses have brought about an increased focus on the importance of quality, safety and efficacy of both MAPs and their produce. MAPs will also maintain their importance in the search for new, valuable sources of drugs and lead compounds. In view of the steadily increasing demands on these important natural resources, attention should be paid to the sustainable forms of production and utilization.

TL;DR: The characteristics studies reveal the properties of embelin from E.ribes berries are on par with the standard embelin received from Sigma (USA), potentially application in cosmetic industries.
Abstract: Summary Embelia ribes one of the Indian traditional medicinal plant, has been used as a cosmetic agent to cure skin disorders for centuries. E.ribes is used especially for dyeing hairs, good pimple remover, treating acne, treating carbuncle infections, treating vitiligo and leucoderma. E.ribes berries contain a quinone derivative embelin (2,5-dihydroxy -3-undecyl,1,4- benzoquinone), has a wide spectrum of biological activities, such as antioxidant, antitumor, anti-inflammatory and analgesic, antihelmintic, antifertility and antimicrobial. Quinone derivatives and the analogs; Ubiquinone (Coenzyme Q10), Idebenone, Arbutin and Hydroquinone are well-known for cosmetic applications. In the present study, embelin from E.ribes berries of Indian origin was extracted and characterized by UV and FTIR analyses. Hemolytic, tyrosinase and DOPA auto-oxidation assays were also carried out. About 1.9± 0.1 gram of pure embelin was obtained from 100 gram of powdered berries (E.ribes). The characteristics studies reveal the properties are on par with the standard embelin received from Sigma (USA). The halfmaximal effective concentration (ED50) of embelin to cause hemolysis was found as 109± 0.1 ug/ml. The tyrosinase inhibitory activity of embelin was nil and the DOPA auto-oxidation activity was observed up to 350 µg /ml concentration. Thus the embelin finds, potentially application in cosmetic industries.

TL;DR: While growth of literature in this field has not been consistent, continued research interest in Lavender has been revealed by this study.
Abstract: Introduction This study evaluates the global scientific output and observes the patterns in the scholarly literature published on Lavender over a period of five years (2008 through 2012). Methods The study is based on the bibliometric analysis of the data collected from two leading indexing and abstracting databases—Thomson Reuter’s Web of Science and Elsevier’s SciVerse Scopus . Results Based on the number of publications during the study period no consistent growth is observed in the research activities pertaining to Lavender. An apparent difference in the research output has been observed between the developed and developing countries. Most of the articles are published in journals from United States, United Kingdom, Netherlands and Germany. Authors have mostly worked in a team of three and have preferred to work with authors from their respective institutions. Authors from over 60 different nations are found to be working on the subject; however, most of them are from Iran, Spain and Portugal. ‘ Lavandula angustifolia ’, ‘ Lavandula stoechas ’, and ‘ Lavandula × intermedia ’ are most extensively studied species. English as a language of publication has remained a prime medium of communication for authors. Conclusion While growth of literature in this field has not been consistent, continued research interest in Lavender has been revealed by this study. Research activity is apparent in a wide range of countries but there is potential for greater international collaboration. The outcomes of research are also widely scattered across numerous journals reflecting the diversity in research being conducted. While the focus has been on a limited number of species of lavender, the large number of available species that have received limited research interest could provide a focus for future research.

TL;DR: Overall, based on the number of publications indexed by both WoS and Scopus, the Asian region, represented by seven countries, are the dominant producers of publications in this field, of which Malaysia is in the number one position.
Abstract: This article has the general aim of assessing the worldwide research productivity of Elaeis guineensis Jacq. and Elaeis oleifera or more commonly known as oil palm, as reflected by the literature indexed in the Web of Science (WoS) and Scopus databases. Specifically, the research aims to identify the most productive countries, institutions and authors in this area of research. It also investigates the subject characteristics of the publication and collaborative patterns among researchers and institutions. Overall, based on the number of publications indexed by both WoS and Scopus, the Asian region, represented by seven countries, are the dominant producers of publications in this field, of which Malaysia is in the number one position. Whereas, USA and some European countries, such as United Kingdom and France, are also leading in terms of publications and citations. Research in the areas of food science and technology (WoS) as well as agricultural and biological sciences (Scopus) account for the highest number of publications. High levels of collaboration among authors are evident among the top 10 most productive countries. This is a good indication of collaboration impact with increased research output. * Department of Library and Information Science, Faculty of Computer Science & Information Technology, University of Malaya, Lembah Pantai, 50603 Kuala Lumpur, Malaysia.

It is thus by far the most widely-produced tropical oil, and constitutes almost 38% of total edible oil production worldwide (Basiron, 2011). From 1998 until late 2008, the international demand for palm oil had increased consistently, leading to alteration in the price of crude palm oil. Over 85% of the world’s crude palm oil comes from Malaysia and Indonesia (Timms, 2007), providing a considerable income to the national and regional governments of these two countries. Since 1970s, Malaysia has strengthened its position as the primary producer and exporter of world palm oil. In line with the very rapid expansion of planted area, Indonesia overtook Malaysia as the world’s biggest palm oil producer in 2007. The global production of palm oil has increased more than nine-fold in the past three decades, supplying the major markets including the European Union, China, Pakistan, India and Indonesia. Significant increases in production were also seen in countries INTRODUCTION Palm oil which is produced from the fruits of the oil palm (Elaeis guineensis Jacq. and Elaeis oleifera) is the second largest edible oil worldwide, after soyabean oil. The Elaeis guineensis Jacq. originated from Africa, whilst the Elaeis oleifera originated from South America. In the past decade, palm oil was the highest produce of the world’s production of oils and fats (Oil World, 2010), exceeding soyabean oil in terms of global production in 2005 (Cheng, 2010). Worldwide, palm oil production for season 2011/2012 was 50.3 million tonnes, increasing to
